Paralleling of power MOSFETs in PFC topology

Introduction
The current handling capability demands on power supply systems to meet high load
current requirements and provide greater margins for overload and reliability, often exceed
the capability of the largest semiconductor devices considered, and their paralleling may
become an attractive alternative. All semiconductor circuits using parallel connected devices
to switch to higher load currents can easily be analyzed by using Kirchoff's law. As long as
